目的探讨糖尿病并发肺结核的影像学特点。方法对95例糖尿病并发肺结核患者进行影像学(X线胸片或CT扫描)检查,同时收集临床资料,分析病灶的特点。结果95例糖尿病并发肺结核患者的病灶表现多为双上肺野分布的多叶、多段的斑片状、大片状阴影和空洞性改变,或表现为急性粟粒性肺结核,单一病灶内多发虫噬状空洞,支气管播散多见。血糖控制后,病灶大多好转。结论糖尿病合并肺结核具有一定的影像学特征:以炎性渗出、干酪变质为主,空洞发生率高,高血糖状态对结核病灶有一定程度的影响。
Objective To investigate the imaging features of pulmonary tuberculosis complicated with diabetes. Methods 95 patients with pulmonary tuberculosis complicated by diabetes were examined by radiography (X-ray or CT scan) and clinical data were collected to analyze the characteristics of the lesions. Results 95 cases of diabetic patients with pulmonary tuberculosis lesions showed mostly double lung field distribution of multi-lobe, multi-segment patchy, large shadows and hollow changes, or the performance of acute miliary tuberculosis, multiple lesions within a single lesion Hollow, more common bronchial dissemination. After the blood glucose control, the lesions mostly improved. Conclusions Diabetes mellitus complicated with pulmonary tuberculosis has some imaging features: inflammatory exudation, cheese metamorphosis, high cavitation rate and hyperglycemia affect tuberculosis to a certain extent.
